Haha alright guys, this may sound really lame but I'm proud of myself for it. Tonight I actually finished my first submission..
I was asked to grapple with a guy named Ta who has just started training this week (I've only been to a few actual grappling classes myself).. He's 28, built like a brick-shithouse, probably has about 30lbs on me and wrestled in highschool, whereas I'm 180lbs, lanky, and have no experience in grappling sports whatsoever.
Anyway, so our instructor starts me off on the bottom, with Ta in side control. As soon as we begin, I can feel how strong of a wrestler this guy is, as he managed to maintain side-control--even managing to switch sides--as I tried scrambling to reclaim half-guard/guard.
Finally, I pulled him into my guard, and I noticed him posture up, so I dropped opened my guard, and scrambled forward, grabbing his left leg for a single and I exploded forward putting him on his back, and myself into his guard. (I really surprised myself here because the guy was so strong and well-versed in wrestling compared to my complete lack of experience.)
Instantly, I broke his guard (using the advice of IronMan in the Back to the Basics thread LOL), and stepped over his legs into side control. As soon as I did this, he shrimped and I stepped over into mount, and he made the mistake of turning completely, consequently giving me his back. Instantly, I managed to get one hook, then the other in while controling his neck to flatten him out. Then suddenly, I threw my hips to the side forcing him to roll, which exposed his neck more, and I locked the choke in, causing him to tap---it reminded me very much of how GSP submitted Trigg with the RNC.
Long story short, I really impressed my coach with my quick-thinking in that situation, which was nice.
Sorry for the long read, I'm just really happy about it.
